If you have a STOCK car with a STOCK IC and a STOCK turbo.... I'd shoot for 11.75 at full boost, whatever that is for your car.

If you are tuning a turbo car and have no experience, I would definitely recommend you take it to a professional. Target AFR is more than just one number, there are many factors involved including the amount of boost you're running, size/type of turbo, timing, intercooler, etc. You shouldn't really shoot for one number across the board if you want your tune to be safe and efficient.

That said, N/A cars are a little simpler (since you didn't specify what car this if for).
